for low fuel consumption and electronic acceleration pedal and rpm set for easy
operation, this power plant supplies

5,772 ft lb of torque.
Maximum Traction Control
Rim pull force is adjustable from 20–100% allowing the operator to make
adjustments with a dial type switch in accordance with operating conditions.
Maximum Speed Control
Travel speed in both first and second gear is adjustable using a simple dial
control adjustment. This allows the operator to find the most effective speed
during his work cycle. Using this control can help decrease tire wear, fuel
consumption, and help to shorten loading cycle times.
Matching With Haul Trucks
Aggressive loading and maximum fill factors lead to exceptional productivity
in the toughest mining conditions.
The WA1200-3 equipped with a

bucket can load a 150-ton truck
in four passes. Due to its extra dumping clearance and reach it is able to load
200-ton trucks in five passes. The high lift version can load 240-ton plus trucks.
Variable Output Hydraulic System (VOHS)
This self-adjusting system puts the power where needed. A variable displacement
pump is employed by this system. When digging, the available traction power
increases and as a result the penetration force increases. When the boom is
raised, the boom hoist circuit flow is increased to provide faster boom hoist cycle
times. This system was designed to lower the machine’s work cycle times.
Hi-Cab
To enhance the loading performance when using larger buckets with the
extra dumping clearance and reach, the hi-cab is standard equipment. From his
vantage point,
6170 mm
20'3" from the ground, the seated operator has a safe,
unobstructed full view of the bucket and the inside of a 240-ton truck body.

Remote Boom Positioner
The highest and lowest position of the bucket can be set
from the operator’s cab to match the height of any truck body.
Once the positioner is set the bucket is smoothly stopped
at the desired position with no shock.
The largest bucket in
its class and the most
advanced technology
available today combine
to make the Mountain
Mover WA1200-3 the most
productive wheel loader.
The Largest Bucket in Its Class
The Mountain Mover WA1200-3 is
equipped with the largest bucket in its
class at

. Komatsu’s bucket
is designed for easy loading with little spillage.
This, combined with the highest traction and
breakout force available, along with the Vari-
able Output Hydraulic System, makes a loader
which achieves high bucket fill factors and
maximum production, able to outproduce
other loaders.
